Ubuntu19.04更新失败现象

最近不知这么的，突然想从kali切换到Ubuntu使用docker，于是下载一个Ubuntu19.04版本，安装好了肯定是先来一波更新，首先换个快一点的源

sudo gedit /etc/apt/sources.list

使用上面目录打开sources.list，然后使用百度来的阿里源替换，源如下;

#阿里云源
deb http://mirrors.aliyun.com/ubuntu/ disco main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ disco main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ disco-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ disco-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ disco-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ disco-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ disco-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ disco-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ disco-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ disco-proposed main restricted universe multiverse

sudo apt-get update

结果没怎么装逼了，就就给报错了

解决方法

打开浏览器，百度一下，谷歌两下，各种搜索，各种尝试，修改地区时间，修改dns，修改源为19.10等等直到把系统玩坏了终于找到原因了：小白的辛酸历程

原来的Ubuntu19.04太旧了，太旧了~ ~ 旧了 ~ ~
因此Ubuntu19.04从存档正式迁移到旧版本存储库中了，因此在更新的时候需要在替换几行源地址或者直接加在源文件后面

deb http://old-releases.ubuntu.com/ubuntu disco main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-security main restricted

总结

搞定了，安装个vim试试
